Perhaps they had never personally faced Ling Tian and the others' attacks before. Perhaps the World-Ending Thunder Dragon had been in terrible condition back then because its Origin Power had been stolen. In any case, the Mist Hidden Sect cultivators hadn't taken the threat of the World-Ending Thunder Dragon too seriously. To them, it was merely a miraculous Saint-grade Heavenly Treasure, unique in the world, that would let them enter the Sacred Ruins Abyss freely.
But when the Mist Hidden Sect and Dark Pavilion faced Ling Tian and the others' ambush head-on, they finally realized how terrifying the World-Ending Thunder Dragon was. Even though their cultivation levels were far higher than Ling Tian's group, they still grew apprehensive when faced with attacks infused with the power of the World-Ending Lightning Tribulation, making it difficult for them to fight at full strength. Some of their disciples had even been killed before their eyes. For a time, they desperately wanted to find a way to counter the power of the World-Ending Lightning Tribulation.
However, from what An Ye and the others could see, even shields and armor forged into Natal Dan Artifacts from materials capable of countering lightning could hardly let them ignore the aura of destruction radiating from the World-Ending Lightning Tribulation. They could only seek some other solution, and An Ye directly asked the Mist Hidden Sect whether they had any way to deal with it.
He had only asked casually, but after a moment's thought, Wu Yi nodded. Without waiting for anyone to ask, he said gravely, "It's not that there's no way. Do you remember an extremely ancient sect called the Thunder Strike Sect? Its cultivators all wield tremendously powerful Lightning Power. Since they control such pure Lightning Power, they must know a great deal about countering it.
